********** account

Vodacom established that my account had a ********** upgrade. After months of waiting they finally said that they closed the account. Now I get a phonecall stating that the account is in arrears and I need a letter from their attorneys to say that the account was ********** before they close it. Now in the meantime my credit record is going down the hill, because of their mistake. They told me I must just send a email requesting this letter. I have sent numerous emails to get a hold of this letter, but no one responds. It has been a month now. I am really fed up with them.
